Saw that in my NYT newsletter. Read it but didn't have to, knew what it would say and I was right. Some decent reactions in comments, though.
There should be a law, an Ordinance on Narrow Competencies: Military historians, for one, should be required to refrain from commenting on anything other than military history, and offer neither media criticism, nor political commentary, nor economic theories, etc.
This would take care of Victor Davis Hanson, John Keegan, and others as well.
